I just found out about this treasure.
It's a minute and fifty-one seconds of rare footage of kung fu masters demonstrating their skill at the 1936 summer Olympics in Germany.
Yes, it is clearly choreographed. Yes it looks hokey.
But only to the untrained eye.
What you are really seeing is a very well orchestrated demonstration of attacks, counters, counters to those counters, take down defense, weapons use, barehanded defense against weapons, and so on.
That pretty much covers all the ground you'd need to know to defend yourself!
It's fascinating to think Bruce Lee was the first to take martial arts "international" but here it is from China to Germany decades before.
